Volley give me only: onErrorResponse

I start to work with volley and when i try to make a post request it give me only errore.
Can you guys tell me when im wrong?
Im working on the Android side of the project with VolleyLibrary.
public class MainActivity extends AppCompatActivity {
private EditText etUsername;
private EditText etPassword;
private Button btnLogin;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etUsername = findViewById(R.id.etUsername);
etPassword = findViewById(R.id.etPassword);
btnLogin = findViewById(R.id.btnLogin);
btnLogin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Login();
}
});
}
private void Login(){
String url = "http://myapies.youcantwatch.it/loginuser_module";
RequestQueue requestQueue = Volley.newRequestQueue(this);
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if(!response.trim().equals("errors")){
Intent intent = new Intent(MainActivity.this, LoggedActivity.class);
startActivity(intent);
} else {
Toast.makeText(MainActivity.this, "Login Fallito", Toast.LENGTH_SHORT).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, "La chiamata non è andata a buon fine", Toast.LENGTH_SHORT).show();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<>();
params.put("firstName","adkdmadm");
params.put("password","asdasdjn");
params.put("secretKey","dlwdmkemd3d455");
params.put("username", etUsername.getText().toString().trim());
params.put("passwordasdad", etPassword.getText().toString().trim());
return super.getParams();
}
};
requestQueue.add(stringRequest);
}
}

Replace StringRequest->JSONObjectRequest and check.
Pass request parameters in JSONObject, not in the header,
only pass Content-Type->application/json in header.

change volley to another libs like retrofit volley long time not updated

Why volley is not sending the values?

I'm new to android development. I'm trying to send some data to server using volley. But it is not sending parameters. Please help. The server is saying that the parameter is not set. I checked with the isset in php. When I tried sending data from a html form, it's working. But the volley is not sending the parameters.
public class MainActivity extends AppCompatActivity {
EditText uname;
EditText uotp;
RequestQueue myqueue;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
uname = (EditText) findViewById(R.id.uname);
uotp = (EditText) findViewById(R.id.uotp);
myqueue = Volley.newRequestQueue(this);
}
public void sendotp(View v)
{
String unameval = uname.getText().toString();
if(unameval.matches(""))
{
Toast.makeText(getApplicationContext(), "Enter Phone Number", Toast.LENGTH_SHORT).show();
}
else
{
HashMap<String, String> params = new HashMap<>();
params.put("phone", unameval);
String myUrl = "http://privateurlhere";
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, myUrl, new JSONObject(params), new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
String dispname = response.getString("stat");
Toast.makeText(getApplicationContext(), dispname, Toast.LENGTH_SHORT).show();
}
catch(JSONException e)
{
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(),"Resp err" + error.toString(), Toast.LENGTH_SHORT).show();
}
});
myqueue.add(request);
}
}
}

Send data to laravel with Android volley

I want to send the user-id data I received with android to laravel.
codes for android;
public class MainActivity extends AppCompatActivity {
public String userId;
Button send;
private static final String KEY_USERNAME ="userId" ;
String insertUrl ="http://127.0.0.1:8000/registerDevices";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
userId= "12345";
send=(Button) findViewById(R.id.buttonPush);
send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Toast.makeText(getApplicationContext(), userId, Toast.LENGTH_LONG).show();
registerUser();
}
});
}
public void registerUser(){
StringRequest stringRequest = new StringRequest(Request.Method.POST, insertUrl,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Toast.makeText(getApplicationContext(), userId, Toast.LENGTH_LONG).show();
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(), error.toString(), Toast.LENGTH_LONG).show();
}
}){

return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
}
My route in laravel;
Route::post('/registerDevices', 'RegisterController#registerdevices');
public function registerdevices(Request $request)
{
\Log::info('api call from andriod');
$jsonPostedData = Input::get('userId');

new Timer().schedule(new TimerTask(){
public void run() {
partietache.this.runOnUiThread(new Runnable() {
#override
public void run() {
finish();
}
});
}
} , 4000);
}
});
#override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (not.isChecked()) {
Toast.makeText(getApplicationContext() , "Notification " + not.getTextOn().toString() , Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext() , "Notification " + not.getTextOff().toString() , Toast.LENGTH_SHORT).show();
}
}

In order to use push notifications you will need to do both server-side and client-side coding. Describing the whole process in detail would be too much for an SO answer, you should take a look at one of the many tutorials available online. Here's one to get you started.

Android: checking database with volley library constantly

I started learning Android and Java a week ago and now I am trying to make an login application. I am using Volley libary to communicate with my server. I have done the login part. Now, what I want to do is to check the database every minute to see if the password or the username somehow changed. If the information in the database is changed, app will automaticly logout the user.
If you can explain which tools(Services,BroadcastReceivers) I can use and how can I achieve it, as I am not very experienced.
This is what I tried and failed:
loginChecker.class
public class loginChecker extends Service {
public loginChecker() {
}
public static String username;
public static String password;
private loginChecker mInstance = this;
public static boolean loginCheck= true;
public static String responseG = "failed";
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Bundle b=intent.getExtras();
username = b.getString("username");
password = b.getString("password");
final String URL = ".........";
final RequestQueue requestQueue = Volley.newRequestQueue(mInstance);
new Thread(new Runnable(){
public void run() {
do{
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
StringRequest request = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
responseG = response;
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
responseG = "error";
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> hashMap = new HashMap<String, String>();
hashMap.put("username", username);
hashMap.put("password", password);
return hashMap;
}
};
requestQueue.add(request);
switch(responseG){
case "successful" :
loginCheck = true;
break;
case "failed" :
loginCheck= false;
break;
case "error" :
loginCheck = false;
break;
}
}
while(loginCheck == true || responseG == "successful");
}
}).start();
Toast.makeText(getApplicationContext(), "LOOP ENDED", Toast.LENGTH_SHORT).show();
return START_REDELIVER_INTENT;
}
#Override
public void onDestroy() {
final Intent mainActivity = new Intent(mInstance, MainActivity.class);
mainActivity.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(mainActivity);
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
}
MainActivity.class
public class MainActivity extends AppCompatActivity {
private RequestQueue requestQueue;
private static final String URL = "........";
private StringRequest request;
private TextView text;
private EditText userName, passWord;
private Button loginButton;
public MainActivity mInstance = this;
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text = (TextView) findViewById(R.id.textView);
userName = (EditText) findViewById(R.id.userName);
passWord = (EditText) findViewById(R.id.passWord);
loginButton = (Button) findViewById(R.id.loginButton);
requestQueue = Volley.newRequestQueue(this);
final Intent profilePage = new Intent(this, Profile.class);
loginButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick (View v){
loginButton.setEnabled(false);
request = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
text.setText(response);
switch(response){
case "successful" :
Intent loginCheckerService = new Intent(mInstance, com.erenyenigul.apps.starter.services.loginChecker.class);
Bundle b = new Bundle();
b.putString("username", String.valueOf(userName.getText()));
b.putString("password", String.valueOf(passWord.getText()));
loginCheckerService.putExtras(b);
startService(loginCheckerService);
startActivity(profilePage);
finish();
break;
case "failed" :
Toast.makeText(getApplicationContext(), "Username or Password you entered is wrong!", Toast.LENGTH_LONG).show();
loginButton.setEnabled(true);
break;
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(), "There is a problem with our servers or you don't have internet connection!", Toast.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> hashMap = new HashMap<String, String>();
hashMap.put("username", userName.getText().toString());
hashMap.put("password", passWord.getText().toString());
return hashMap;
}
};
requestQueue.add(request);
}
}
);
}
}
There is also a file called Profile.class but it is empty. I tried this but the loop lasted one tour. It stopped even though the connection was ok and the data wasn't changed.
